[PATCH 1/2] archimport: allow for old style branch and public tag names

[Eric Wong <normalperson@yhbt.net>]

This patch adds the -o switch, which lets old trees tracked by
git-archmirror continue working with their old branch and tag names
to make life easier for people tracking your tree.

Private tags that are only used internally by git-archimport continue to be
new-style, and automatically converted upon first run.
